Abstract: A differential is provided that includes a case, a cam side gear disposed proximate a first end of the case, and a side gear disposed proximate a second end of the case. The side gears have respective hubs. The differential further includes a first clutch pack disposed around the hub of the side gear. The differential further includes an annular engaging member disposed between the side gear and the case.

Abstract: A differential is provided that includes a first and second side gear and a reaction block disposed between the first and second side gear. The differential further includes an engagement mechanism configured to have at least a portion of the engagement mechanism that is moveable from a retracted position to an extended position and a lock-out mechanism that is configured to engage the portion of the engagement mechanism. The lock-out mechanism is mounted to the reaction block. A reaction block for a differential in which a lock-out mechanism is mounted on the reaction block is also provided.

Abstract: An improved differential gear mechanism is characterized by a cam mechanism including a first cam member fixed to rotate with one of said output gears and a second cam member free to rotate relative to said first cam member and said output gear. The first cam member defines a first cam surface and the second cam member defines a second cam surface engagable with the first cam surface to impart movement of the second cam member along axis. The first cam member comprises a powdered metal component, which provides consistency in the cam surface profile and eliminates the substantial capital equipment needed to machine the cam surface.

Abstract: A torsion isolator assembly (30) for reducing driveline torsionals includes a vane damper (36) including improved valving (40d, 40e) for increasing the damping factor of the damper, improved spiral springs (32,34 or 80,82) for reducing spring stress primarily due to centrifugal forces, and cam surfaces (44d,44c) for further reducing spring stress due to centrifugal forces.
